LIFE-SAVING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 671,185, dated April 2,1901.

Application filed July 9, 1900. Serial No. 22,971. (No model.)

To all whom it nutty concern:

Be it known that I, JoReEN MARTINIUS D6NVIG, a subject of the King ofNorway and Sweden, residing at the city of Christiania, Norway, haveinvented new and useful Improvements in Life-Saving Apparatus, of whichthe following, taken in connection with the accompanying drawings,is aspecification.

This invention has for its object the construction of a life-saving buoyserving as refuge for the passengers and the crew in cases of emergencyinstead of the present life-boats.

In the accompanying drawings, Figure 1 is an elevation of the buoy. Fig.2 is a plan View of the same. Fig. 3 is a vertical section through thecenter of the buoy. Fig. 4: is a plan sectional view on the line a: inFig. 3. Fig. 5 is an enlarged sectional elevation of the ventilatingarrangement. Fig. 6 is a plan sectional view of the same. Fig. 7 is asection through the manhole. Fig. 8 is a plan view of the manhole-cover.Figs. 9 and 10 are details of locking mechanism of the manhole-cover.Fig. 11 is an enlarged sectional view of one of the pillars containingthe upward-movable telescopic tube. Fig. 12 is an enlarged sectionalview of one of the pillars containing the downward-movable telescopictube. Fig. 13 is an elevation of a modified construction of the buoy.Fig. 14 is a plan view of the same. Fig. 15 is a vertical sectionthrough the center of the buoy. Fig. 16 is a plan sectional view on theline y y in Fig. 15.

The buoy or globe A, which is built of plates of iron, steel, or othersuitable material, is preferably provided with a flat bottom in order tohave a base to stand on if landing on a fiat shore. At a suitabledistance from the bottom the globe is provided with a watertight floor(1, thereby forming a room between said floor and bottom for thereception of ballast, which properly might consist of. fresh water. Thesaid roomshould be divided by partition a in compartments, so that assoon as one compartment is emptied of fresh water it may be filled withsea-water, and by this arrangement only one compartment at a time willbe less than full. The more compartments the less will be the efliect ofone being empty or partly empty. The filling of the compartments withsea-water may be carried out in any convenient way-for instance, bymeans of a hose connect-ed to a valve on the side Wall of the globe andto the connectingpiece 19 (one for each compartment) on the floor.

Above the floor an annular wall Z) is joined water-tight to the floorand to the side of the globe, thus forming along the side astoragelOOll] in which may be stored supplies of food, tools, and otherimplements necessary for the voyage. This room is also divided bypartitions 17' into several compartments, which are accessible throughopenings closed watertight by covers 11 The floor is sloping inalldirections toward a gutter a, running at the foot of the wall I). Thesaid gutter empties into a basin a which gathers any waste (Water, the.)and from which the waste may be drawn by laying a hose from the basinupto a sucking and forcing pump cl, placed inside the globe for thispurpose and which sends the waste out through the wall of the globe intothe sea.

A ventilating arrangement is provided for at the top part of the globe.The said arrangement consists of an outer cylinder 6, (see enlargedView, Figs. 5 and 6,) fastened to the globe. Inside this cylinder ismounted another cylinder c, which turns in the first one. Both cylindersare provided with apertures 6 6 which correspond in a certain positionof the inner cylinder. The outer cylinder c has its upper edge somewhatwidened, and it is covered by a lid f, fitting water-tight into the saidwidened part of the cylinder c. The said lid is mounted on the top endof a rod f, guided in two cross-pieces g g and having a spring f bywhich the lid f is kept closed. The cylinder e is provided with an arm 6and is kept closed by a spring 6 being fastened to the end of said armand to some place within the globe. e is a cord by means of which thecylinder e can be turned so that its apertures 6 will correspond withthe apertures c in the cylinder 6. It will be seen that the cylindersand the lidf are normally kept closed by springs. Should it, however, bede-' sirable to keep the lid f open for a time, a catch-leverf isjournaled on the lower crosspiece g and made to engage a collar f on therod f. The springf will secure the engage ment of the lever with thecollar f and by pulling the cord f the lever is disengaged. Theventilating arrangement is protected by means of a cage or open casingG.

The globe is outside provided with a girder of cork B, which will serveas a fender.

Just above the girder B are provided entrance-openings which are closedby covers 0, opening inwardly. Said covers are shut by an efficientlocking device, Figs. 9 and 10, consisting of a latch c, which slides inguides c c and engages a cramp-iron 0 The latch c is moved by means ofan eccentric c on the handle-bar 0 The outer handle 0 is placed in arecess in the lid 0, so as to protect it from being knocked off. The lid0 is provided with a packing-ring C in order to obtain water-tightclosure of the opening.

JJare light-openings,in which are mounted thick panes of glass.

The globe is internally provided with a number of vertical hollo-wpillars or columns K K K K intended in the first place to strengthen theglobe; but they are also intended to receive telescopic tubes 10, whichare movable by means of tubular handles projecting through slots in thepillars. The ends of the pillars or outer tubes are closed by plugs 70which are easily removable when projecting the tubes 7c.' In two of thepillars-for instance, the two diametrically opposite each other-thetelescopic tubes are arranged to be moved upward through the top of theglobe, while the tubes in the other two pillars are arranged to be moveddownward through the bottom of the globe. To secure against any inlet ofwater, the latter pillars are provided with a valve m.

10 represents packing-rings, of which the ones next to the handles itare fixed on the tubes and serve as guides, while the other ones arefixed in the pillar and should prevent any inlet of water.

The object of the arrangement of the upwardly-projectable telescopictubes is to provide for ventilation in case the above-describedventilating arrangement (the cylinders e 6) should get out of gear andin rough weather, as the tubes when projected will let the air haveaccess through the hollow handles 7t and yet prevent any inlet of water.The tubes movable downward are to be usedshould the globe be thrownashore and remain with the bottom up.

For the pumping of fresh water from the ballast-tanks a pump P is placedon the wall of the globe, and the water may be drawn by means of a hoseconnected to the pump and the nipples p on the floor. The globe isfurther provided internally with rods 25, Fig. 3, removably mounted insockets t on the wall I) and fastened in brackets t on the pillars.These rods will serve as supports or handles for the personnel in roughweather, and they might bemade in the shape of oarhandles, the bladesbeing detached when the handles are in place and screwed on when theyshall be used to paddle with.

R is an anchor with collapsible fluke arms of the ordinary type, theline 7 of which is coiled around the middle of the globe just under thecork fender B. The line is his tened to an eyebolt s and passed throughanother eyebolt s, placed so that the pull of the line shall not heaveover the globe. In order to stop the paying out of the line whendesired, a hook it is journaled in the side of the globe and providedwith a handle by which it may be turned from the inside. The object ofthe said anchor is to provide means by which the globe may be stoppedshould the coast not be favorable for landing in stormy weather.

In Figs. 13, 14, 15, and 16 is shown another construction of the globe,specially with regard to the ventilating arrangement, which in this caseis placed inside the globe altogether. The outer cylinder e is in thiscase reduced to a small ring, which fits watertight around the cylinderc'. The latter slides in the ring 6 and is closed water-tight at the topby a cover or lidf. The cover is mounted 011 the upper end of a rod f,which slides in cross-pieces g g. The cover is closed nor mally by meansof a spring f and may be opened by forcing the handle of the rod upward.The cylinder 6 is guided by two guiderodsV and is moved by means of ahandle h. In order to hold the cylinder in different positions, the rodsV are provided with hooks 12, which engage with the guide-lugs Q) on thecylinder. By this arrangement there is no danger of destroying theventilating arrangement, because the cylinder 6' is not projected beforethe globe is perfectly clear of the ship. As a further protection of theglobe a number of cleats Z are mounted on the upper part of the same.The globe is further provided with a well W between the floor a and thebottom of the globe. The well is securely closed by a cover 10. Theobject of this well is to provide for an outlet through the bottom ofthe globe in case it should be thrown ashore with the bottom side up.The well should therefore have an oval shape. By this arrangement aneasy way of filling the fresh-water compartments with sea-water isobtained by opening the plugs to. Should it be found that theabove-mentioned well W reduces the space for the ballast too much, thebottom of the well may also be closed by a water-tight cover and emptiedthrough an opening in the upper cover w. Otherwise this globe isequipped in the same manner as the globe described in connection withFigs. 1 to 12.-

Finally, it should be mentioned that the globe is internally providedwith frames 2 like a ship and externally with rolling bilgekeels B. r

Although the above specification fairly sets forth the object of theinvention proper, it should be mentioned that the globe when carried outpractically should be furnished with such appliances as will tend to thesafety and convenience of the persons contained therein. Thus, forinstance, the walls should be padded inside, and a partition of canvasor netting should be stretched across the space a little distance belowthe manholes, the object being principally to gather children and weakpersons and prevent them from being thrown down violently on the floorin the scramble, and also to prevent harm to persons already inside incase the globe should be upset in launching from the ship. it The wallI) should be built so as to form an annu lar lounge, and the floorshould be covered with a wooden grating, and so on. In fact, everyobject of hard material should be covered by some soft material, so asnot to hurt the persons during the launching of the globe from the ship.

Finally, it should be mentioned that the cork fender B may be extendedto cover the whole of the upper surface of the globe, only leavingspaces for the entrance-openings, the ventilating-cylinder and tubes,and the lightopenings.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat Iclaim is- 1. An improved life-saving buoy formed with an interiorlife-saving chamber, a ballasted bottom, vertical hollowstrengtheningpillars extending upward from said bottom and openingthrough the top, and ventilatingtubes playing telescopically in saidpillars and communicating with the interior of the buoy through hollowhandles or knobs projecting through longitudinal slots in said pillars.
